,TO ALL WHOM IT MAY GONOERNi Be it known'that I, JABlEZ BURNS, of No. 269-Washington street, in the city, county, and State of New York, have invented a new andimproved Apparatus for Mixing-Powders, 850.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enablethose skilled in the art to makeand use the some, reference being had to the accompanying drawing, forming a part of this, specification, in which Figure 1 represents a horizontal section of this inventioni Figure 2'is a transverse section thereof.

Similar letters of reference in both views indicate corresponding parts.

This'invention relatesto an apparatus which is intended'for miicing granulatedsubstances, such as ground codes or powders-of any description. It consists in the arrangement of a movable agitator in the interior of a drum,:to which a revolving motion can be imparted by somesuitable mechanism, and which is provided with a feed opening-in such a manner that said agitator can be readily removed and cleaned whenever the mixer is to be used 'for inaterialsmf difierent nature. i

The agitator is constructed of a series'of spiral flanges, which are secured to one of the heads of the drum, and said head is made movable, so that by the action of the spiral flanges the materials to be mixed are thrown towards the movahle-head, and if said head-is drawn out a short distance it serves as an abutment, preventing thematei'iaI from being scattered, an d con ducting it into a barrel or othe'r su'itabl'e receptacle below-T I A represents a cylindrical drum, made of sheet-meta-l'or' any other suitablematerial', and of any desirable size. This drum isprovided with two on more rims, a, which rest on flat or grooved pulleys. or rollers, 6, the axles of which have their hearings in arms or standards B, so that arevolving motion canbe imparted to said drumby hand or by any-other suitable power. -It must be remarked, however, that the drum maybe supported in, any other suitable manner, provided it be so arranged that a revolving motion canb'e imparted to it,'and I do not wish to confine myself toany peculiar manner of supporting the drum, neither do I wish to restrict m yself to any particular mechanism for imparting motion to said drum. The drum A is provided with two heads, 0 0, one of which is fi'xed and, the other movable. The fixed heads is provided with a feed opening,

(2, through which the material to be mixed is introduced. The movable head is provided with a handle, e, by means .of which the same can be drawn out of the drum, and from its inner surface projects the agitator C. This agitator is composed of a series of-spiral flanges, ff, which run in opposite directions,'and which are so arranged thatby the outer flanges futhe material to be mixed is carried -in-one' direction, and by the; inner flangesf' it is carried in the opposite direction, and that by their; combined action the material fed into the drum is returned over and over again and thoroughlymixed. When theoperationof mixing is finished, the head 0', together with theagitator, can be readily withdrawn and all the vparts can be easily cleaned, which is absolutely necessary whenever the mixer is to be used for different inater ials, such as ground cofi'ee, pepper,

or spices-of difl'er'ent kind, or for chemicals.

By these means a mixer is obtained which effects the desired object thoroughly and with great rapidity,

and which can b used for powders or granulated substanoes of every kind...

What I claim 'as new, and desire to secure by'Letters Patent, is-

Thespiralflanges'fff, running in opposite.directions, in combination with the movable head a, drum A,

and standards B,-with band and friction-rollers, constructed andoperating substantially as and for the purpose set forth.
